Treatment

Edessa (Edessa) maurocornis sp. n.

( Figs. 32 View FIGURE 32 , 64 C–D View FIGURE 64 , 73 View FIGURE 73 )

Etymology. The name refers to the black humeral angles in dorsal view (Gr. mauros, dark; L. cornu, horn).

Material examined. Holotype male. BRAZIL, Amazonas : Manaus ZF-2 KM 14 35 m, torre, 09–12-XI-2004, C. S. Motta, A. S. Filho, S. Trovisco, L. S. Aquino (S W 0235215 600655) ( INPA).

Measurements (n= 1). Total length: 18.1; head length: 1.9; head width: 3.3; pronotum length: 3.8; pronotum width: 13.2; scutellum length: 8.4; scutellum width: 6.2; abdominal width: 10.6; length antennomeres: I: 1.0; II: 1.2; III: 1.9.

Diagnosis. Large (18.1 mm). Dorsal body surface olive green, densely punctured ( Fig. 64 C View FIGURE 64 ). Ventral surface yellow with transversal brown bands on thorax and abdomen ( Fig. 64 D View FIGURE 64 ). Antennae reddish brown ( Fig. 64 C View FIGURE 64 ). Pronotum with brown punctures ( Fig. 64 C View FIGURE 64 ); anterolateral margin and cicatrices with brown punctures. Humeral angles as long as wide; laterally directed; apex with black spot restricted to the angles in dorsal view and restricted to the margin of the angles in ventral view, remaining of the spot brown ( Fig. 64 C–D View FIGURE 64 ). Scutellum with brown punctures; posterior part excavated medially; apex acute not reach end of coria ( Fig. 64 C View FIGURE 64 ). Coria with all veins yellow ( Fig. 64 C View FIGURE 64 ). Connexival segments with concavities slightly covered by elliptical brown spots ( Fig. 64 C View FIGURE 64 ), spots not extending ventrally ( Fig. 64 D View FIGURE 64 ). Posterolateral angles of connexivum with apices brown ( Fig. 64 C View FIGURE 64 ).

Ventral surface, thorax with brown bands; dark band of the propleura covering 2/3 of the width of the sclerite ( Fig. 64 D View FIGURE 64 ). Proepisternum with dark band ( Fig. 64 D View FIGURE 64 ). Evaporatorium concolorous with the surrounding surface ( Fig. 64 D View FIGURE 64 ). Metasternal process ( Figs. 32 F View FIGURE 32 , 64 D View FIGURE 64 ) with arms of anterior bifurcation straight and laterally expanded at apex; anterior bifurcation somewhat excavated receiving fourth of the rostral segment. Legs brown ( Fig. 64 D View FIGURE 64 ). Abdomen with spine of segment III rounded ( Fig. 32 F View FIGURE 32 ). Intersegmental areas covered by wide and dark brown to black bands with smudged margins, not reaching lateral margin ( Fig. 64 D View FIGURE 64 ). Pseudosutures smoky brown to black with irregular margins ( Fig. 64 D View FIGURE 64 ). Median longitudinal brown band incomplete ( Fig. 64 D View FIGURE 64 ). Trichobothria one in line with spiracle and the other laterad. Male genital, dorsal side of the pygophore with a suffused dark area occupying 1/3 of the surface ( Fig. 32 A–B View FIGURE 32 ). Posterolateral angles of pygophore slightly developed, narrow ( Fig. 32 A View FIGURE 32 ). Superior processes of the genital cup high, rectangular, thick, concave in posterior view and continuing ventrally in a well-developed and thick projection; this projection with truncated apex and thickness does not change until apex ( Fig. 32 A–B, C– D View FIGURE 32 ). Diaphragm with contrasting yellow spot ( Fig. 32 D–E View FIGURE 32 ). Parameres ( Fig. 32 D–E View FIGURE 32 ) with black margins; anterior lobe subrectangular, well projected; dorsal lobe subtriangular; posterior lobe subrectangular. Proctiger, anterior face half black ( Fig. 32 D–E View FIGURE 32 ); posterior face subelliptical ( Fig. 32 D–E View FIGURE 32 ). Ventral surface densely punctured, punctures in “V”; with suffused dark spots near the ventral rim, laterally and medially ( Fig. 32 C View FIGURE 32 ). Ventral rim with long setae but without a lateral tuft ( Fig. 32 C View FIGURE 32 ); with expansions little developed, rounded, concolorous with the surrounding surface, expansions at the same level as the of posterolateral angles ( Fig. 32 C View FIGURE 32 ). Female genitalia. Unknown.

Comments. See comments on E. (E.) atricornis sp. n.. Edessa (E.) maurocornis sp. n. differs from E. (E.) atricornis sp. n., E. (E.) fuliginocornis sp. n., and E. (E.) illuminocornis sp. n. by the ventral body bands wide and somewhat vivid (the other species with ventral body bands narrow and faded).

Distribution ( Fig. 73 View FIGURE 73 ). BRAZIL: Amazonas.
